Specification of Letters Patent.

Patented July 27, 1909.

Application filed June 11, 1908. Serial No. 437,956.

To all whom it may concern:

Be it known that I, CHRISTOPHER F. PLUNKETT, a citizen of the UnitedStates of America, residing in the borough of Manhattan, in the city,county, and State of New York, have invented certain new and usefulImprovements in Siphons, of which the following is a specification.

This invention relates to siphons, and par ticularly to a device forsecuring the usual siphon head on the bottle, the object of my inventionbeing to provide simpler and more efiicient means for this purpose thanthose hitherto in use.

In the accompanying drawings in which my invention is illustrated Figure1 is a perspective view of a bottle neck formed in accordance with onemethod of carrying out my invention; Fig. 2 is a perspective View of theusual threaded ring adapted to be used with said bottle; Fig. 3 is asection of the bottle shoulder on a line passing through the upperportion of the bayonet slot 14 shown in Fig. 1; Fig. 4 is a verticalbroken,

section showing a siphon head applied to the bottle.

In securing siphon heads on seltzer bottles and the like it is nowcustomary to supply a split ring which is threaded on its exterior faceand fits beneath a shoulder on the bottle neck. The siphon head isprovided with a depending skirt which is internally threaded to engagethe split ring whereby the head may be screwed down tight on the bottleneck. The use of a split ring is accompanied by many inconveniences,however, since it is difficult to hold the halves in proper positionwith relation to their threads when adjusting the head; furthermore,when the head is detached, the halves fall apart and arereadilymisplaced or lost; special clamping means must be employed alsoto hold the ring from swiveling around the bottle neck when it isdesired to screw the head on tight, and more especially when it isdesired to unscrew the head for the purpose of washing and filling thebottle. These disadvantages are avoided by making the ring 10 integraland providing suitable means for securing the same beneath the shoulders11 of the bottle neck. While any suitable means for this purpose may beemployed, a simple method is illustrated in Figs. 1 to 4. Lugs 12, whichmay be of any desired number, are formed on the inner face of the ring10, and slots 13 corresponding in number are cut in the shoulder 11 forthe passage of these lugs when the ring is slipped over the bottle neck.When the ring is below the shoulder, it is turned slightly until thelugs are in position to enter bayonet slots 14 also formed in theshoulder. The ring is then lifted so that the lugs pass into theseslots. In this position the ring is locked so that it will not swivelwhile either attaching or detaching the head 15, there is no annoyanceor delay in adjusting the threads, since the ring is integral andthe'threads continuous, and furthermore, when the head is removed thering remains in place upon the bottle, although it is readily removed ifso desired. Should the bottle be broken, the ring may be quicklyadjusted to another. Other means may be devised of accomplishing thesame end without departing from my invention, and I do not limit myselfto the constructions shown.

I claim as my invention 1. A device of the character described,comprising an integral rigid ring externally threaded to receive asiphon head, and provided with an inwardly projecting lug, incombination with a bottle having a shouldered neck bayonet slotted toform, in combination with said lug, a lock whereby said ring is rigidlysecured beneath said shoulder substantially as described.

2. A device of the character described, comprising an integral rigidring externally threaded to receive a siphon head, and provided with aninwardly projecting lug, in combination with a bottle bearing ashouldered neck slotted to permit the passage of said lug beneath theshoulder and slotted in bayonet form to form, in connection with saidlug, a lock whereby said ring is rigidly secured against rotation,substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.

CHRISTOPHER F. PLUNKETT.
